Product Description
304 Stainless Steel Capillary Side Hole Puncture Spray Needle
304 Stainless Steel Medical Grade Capillary Puncture Needle with Precision Side-Hole Drilling for Radial Fluid Dispersion 0 304 Stainless Steel Medical Grade Capillary Puncture Needle with Precision Side-Hole Drilling for Radial Fluid Dispersion 1
The 304 Stainless Steel Capillary Tubing Side-Hole Puncture and Spray Needle is a specialized medical and industrial instrument engineered for precise fluid delivery or aspiration through lateral openings. Manufactured from medical-grade 304 stainless steel capillary tubing, it features a closed, sharpened tip for penetration and precision-drilled side holes near the distal end. This unique configuration enables radial dispersion or collection of fluids, reducing forward jet pressure and facilitating targeted delivery in confined or delicate environments.
Manufacturing Process
  • Material Preparation: Selection and cutting of certified 304 stainless steel capillary tubing to specified lengths
  • Tip Sharpening: Precision grinding of distal end to form sharp, closed tip configurations
  • Side-Hole Drilling: Micro-drilling or laser ablation of lateral holes at precise locations and angles
  • Deburring & Cleaning: Meticulous removal of burrs followed by ultrasonic cleaning
  • Surface Finishing: Electropolishing and passivation for smooth, corrosion-resistant surfaces
  • Hub Assembly: Attachment of Luer-Lock or standard connectors to proximal end
  • Inspection & Testing: Dimensional verification, visual inspection, and functional flow/pressure testing
  • Sterilization & Packaging: Sterilization and clean packaging for medical applications
Applications
Medical Interventional Procedures
  • Angiography and embolization for contrast agent or embolic material delivery
  • Abscess and cyst drainage for fluid aspiration
  • Nerve blocks for circumferential anesthetic distribution
  • Tumor ablation for ethanol or chemotherapeutic agent injection
Laboratory & Analytical Chemistry
  • Chromatography as solvent spray needle for Mass Spectrometry
  • Micro-dispensing for precise reagent delivery
Industrial Processes
  • Precision lubrication of bearings and small mechanisms
  • Adhesive and sealant application in micro-assembly
  • Cleaning and spraying in confined spaces
Technical Specifications
Parameter Category Specification Details & Options
Material Tubing Material 304 Stainless Steel (Medical Grade, ASTM A269/A632) - Excellent corrosion resistance, strength, and formability
Design Tip Configuration Closed Tip: Sharpened for penetration (Bevel, Trocar, Pencil Point)
Side-Hole Configuration Number of Holes: 1, 2, 3, or more
Hole Pattern: Radial, helical, or custom
Hole Shape: Round, oval, or slot configurations
Dimensions Outer Diameter (OD) Typical Range: 0.3 mm to 2.0 mm (30G to 14G equivalent)
Inner Diameter (ID) Typical Range: 0.1 mm to 1.5 mm (dependent on wall thickness)
Wall Thickness Customizable for specific pressure requirements
Overall Length Common: 50 mm to 300 mm - Custom lengths available
Hole Specifications Hole Diameter Typical: 0.05 mm to 0.5 mm - Proportional to tubing OD/ID
Hole Drilling Tolerance Position: ±0.05 mm
Diameter: ±0.01 mm
Performance Flow Characteristics Designed for radial or angled fluid dispersion - Reduces high-velocity forward jetting
Pressure Rating Standard designs suitable for pressures up to 50-300 bar (700-4500 psi)
Surface Finish External & Internal Electropolished - Smooth finish (Ra ≤ 0.4 µm) minimizes flow resistance
End Connection Medical Standard Luer Lock Hub (ISO 594)
Industrial/Lab Luer Lock, ¼-28 flat-bottom fittings, compression fittings, or custom
Tolerances Overall Dimensions Length: ±0.5 mm
OD: ±0.01 mm
Key Feature Advantage
Enables targeted fluid delivery adjacent to, rather than directly ahead of, the needle tip. This critical feature is essential for coating surfaces, filling cavities, or avoiding damage to tissue and structures beyond the tip.
